El equipo de investigaci\u00f3n de seguridad <strong>Ledger Donjon<\/strong> identific\u00f3 la falla, que afecta a las tarjetas de Tangem Wallet, considerada una de las opciones m\u00e1s accesibles del mercado en t\u00e9rminos de costo-beneficio.<\/p>\n<p>Seg\u00fan la investigaci\u00f3n, la brecha permite realizar <strong>ataques de fuerza bruta<\/strong> mediante una t\u00e9cnica llamada \u201cpower glitching\u201d o \u201cca\u00edda de energ\u00eda\u201d. Este m\u00e9todo aumenta la tolerancia a fallos al introducir el <strong>PIN de desbloqueo<\/strong>. En la pr\u00e1ctica, puede <strong>acelerar los intentos de adivinar la contrase\u00f1a de los usuarios.<\/strong><\/p>\n<p>Las pruebas de <strong>Ledger Donjon<\/strong> demostraron que los atacantes pueden manipular el contador de errores de autenticaci\u00f3n de Tangem al cortar la energ\u00eda del dispositivo en el momento exacto. Esto impide que se registren los intentos fallidos y permite realizar hasta <strong>2,5 combinaciones por segundo.<\/strong><\/p>\n<p>Esa t\u00e9cnica reduce de manera dr\u00e1stica el tiempo necesario para romper contrase\u00f1as cortas. Un atacante podr\u00eda descubrir un <strong>PIN de cuatro d\u00edgitos<\/strong> en una hora, cuando normalmente se necesitar\u00edan cinco d\u00edas debido a los mecanismos de seguridad del dispositivo. En el caso de c\u00f3digos m\u00e1s largos, como los de seis u ocho d\u00edgitos, a\u00fan ser\u00edan necesarios meses o a\u00f1os.<\/p>\n<p>El <a href=\"https:\/\/x.com\/P3b7_\/status\/1968313961486614723\"><strong>CTO de Ledger<\/strong> <\/a>destac\u00f3 que los riesgos son mayores para quienes utilizan contrase\u00f1as simples o comunes.
